Soft tissue sarcomas are rare disease and the development of efficacious drug is urgently needed. The challenge is continuing, and recently 2 drugs, trabectedin and eribulin, were approved in Japan. Both drugs were investigated in patients with liposarcoma or leiomyosarcoma in randomized phase III trials as compared to dacarbazine. Eribulin was superior in terms of overall survival and trabectedin was superior in terms of progression-free survival compared to dacarbazine. This article reviews the efficacy and safety of both drugs.
